    Abstract: An upper electrode used for a substrate processing apparatus using plasma is provided. The upper electrode includes a bottom surface including a center region and an edge region having a ring shape and surrounding the center region, a first protrusion portion protruding toward plasma from the edge region and having a ring shape, wherein the first protrusion portion includes a first apex corresponding to a radial local maximum point toward the plasma, and a first distance, which is a radial-direction distance between the first apex and a center axis of the upper electrode, is greater than a radius of a substrate.

    Abstract: A post baking apparatus comprising a baking chamber configured to receive a substrate with an exposed photoresist film, a lower heater in the baking chamber under the substrate to heat the exposed photoresist film, an applier applying an electric field or a magnetic field to the exposed photoresist film along a vertical direction, which is substantially perpendicular to an upper surface of the exposed photoresist film, to control diffusions of an acid or a secondary electron, which are generated from the exposed photoresist film, along a horizontal direction, and a controller configured to control an operation of the applier.
